Packaging & Shipping
Male/Female rod, speed rod:
MF drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. MF drill steel procides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with MF steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.
For extension rod and MF steel process, the below two different types of heat treatment are used to strengthen high speed and powerful percussive drill string components to maximize their performance and reliability. Longer steel larger in diameter, conventional extension steel, Hexagonal and round cross sections are available.
Carburization is a process used to harder the entire rod surface both internally and externally to strengthen and extend the life of the rod.
High frequency induction is process where only the thread ends of the rod are hardened to lengthen thread life.
